- Page 9 The central controller creates messages and transmits them to the VFC-3000 controller for storage. Upon request from the central controller or the front panel interface, the VFC-3000 controller locates the message to display and sends it to the display’s modules via the distribution board.
- Page 11 Section 2: Components 2.1 Modules A module is a replaceable unit consisting of a display panel with clusters of LEDs, called pixels, and a driver board. The pixels show messages on the display face. Refer to Figure 2. Each module contains drive electronics, which receive data packets from the distribution board and light the appropriate pixels at the correct dimming level.
- Page 12 2.3 Control Panel The control panel is located in the right side of the display. Figure 4 shows what components make up the control panel. These components use information received from the VFC-3000 controller to operate the display.

- Page 13 2.6 Relays Relays are solid-state switches in which the electrical current applied across one port or terminal controls electrical currents for another terminal, such as a beacon or fan. Relays receive signal from and transmit signal to the CAN I/O board, which communicates the relay’s status to the CAN distribution board.
- Page 14 2.9 Beacon(s) (Optional) Beacons are turned on and off independently from the rest of the display by the CAN I/O board. The CAN I/O board interfaces with the beacon control panel (BCP), located on the rear wall. A power supply and DC relays are located within the BCP. Beacons are used only during certain messages, such as emergencies or warnings, as an extra measure of alert.
- Page 15 Cabinet Heater (Optional) If equipped, the heater fan is located at the bottom of the traffic cabinet. The fan, thermostat, and heater regulate the temperature within the traffic cabinet, ensuring internal components operate at ideal temperatures. UPS (Optional) A UPS contains batteries and an inverter. If the utility AC power fails, the UPS powers the VFC-3000 controller and communication equipment for a limited amount of time.
